The time of Earth
Throughout since time earth has been having many different anomalies with it's general appearance as a blue planet but it wasn't always it was looking like that with supercontinents to the existence of organisms over the past millions of years it's been it's been changing it's look to something out of the ordinary.
At the beginning with the formation of our known planet earth many the known species of animals animals didn't exist at that time since most of the prokaryotic microbes and bacteria when the earth formed did not evolve yet living many of the species we know if of didn't arrive at that time prokaryotic microbes were the only organisms thriving on earth. Different kinds of bacteria roamed around the Eco-systems most of them dissolved minerals to eat and migrated there way around the continents until lots of them ended up in different regions of the world, the theory of prokaryotic microbes is they don't carry a membrane-bound nucleus their DNA is circular and don't have a shield of skin.
In the formation of early life there was a phenomena that accrued 55.6 millions years ago called the Cambrian event, what had happened during this period was the beginning of animals, earth's climate and species while most animal phyla appeared at fossils of their development when this happened it lasted 13-25 millions years and resulted in the divergence of most modern metazoan phyla and the emergence of different species being brought to life that made the very first event of modern life in the history of Earth! "the event was accompanied by major diversification of other organisms", it began 541 millions years ago then after the explosion a world the Triassic period started.
Having to know what life was like a few years after the Cambrian explosion was soon only a development of life containing forms of species as time extends beginning to spread through the regions of the continents many life forms appeared to be marine species that surrounded the Ediacaran period 94 million years form the end of the Cryogenian period 635 million years ago but this geological event could have started cause our planet's axis tilt and shifted drastically upon contacting force deep beneath earth's mantle, modifying climate rhymes.
This event not only changed the environmental habitat for organisms is also shifted the planets' climate with earths tropical glaciers. In the 1960s a geologist named Brain Harland brought up a startling discovery. He found that in the Precambrian glaciers had formed at sea-level near the equator suggesting that tropical regions must have been cooler back then. Researchers came up with several theories to resolve this conundrum! one of them is our planets could of become a Snowball Earth!.
The important biological innovations of those periods commonly attributed to the ''snowball Earth'' may be allied to massive environmental perturbations accompanying the proposed impact could have blown portion of the ocean into the atmosphere! this would provide a plausible mechanism for the oxygenation of the oceans.
Earth's past has many different events accruing with it's climate changing every so thousands of years this could lead to many glaciers forming with in the regions and mountains would turn out bigger, seasons would increase in Summer and winters be extended but near 600 to 450 million years ago many differences make of it's past change as more of the super continents tend to be breaking apart as earth gets older the story of it past is quite "unusual" in the early Ediacaran period there was a super continent called Pannonia from Greek ''Pan''
with most of the Pacific ocean was more extended but during this climate the early Ordovician most of the planet at this time was generally cold during the early Cambrian probably due to the ancient super continent Gondwanan covering the South Pole and cutting of the polar ocean currents.
Throughout Ordovician period most of the continents we know today have long past separated into different regions cause of the tectonic plates under the land mass of square areas of land, but as the regions separated most of earths super continents began to disappear and our specific ocean began to decrease, this is the result of shiftiest with tectonic areas moving!, this sequence managed to change over time until reaching the very map you see today! but as time passes many discovers are still be covered, so back during the Ediacaran period only a few supercontinents existed at that time Gondwanan, Pannonia and Laurasia Gondwanan a Vendean African supercontinent but at that time period life in the sea was beginning to emerge in that region and multicellular life forms was beginning to exist.
Now reach 40 millions years later and more phenomena is accruing through increasing amount of life forms to sudden changes seasons but with this comes more anomalies, in the late Ediacaran period Bacteria and algae were more common in the seas, as were the enigmatic acritarches, planktonic single-celled algae of uncertain affinity. But during the Ediacaran period one of it's discoveries the Ediacaran time also marks the first appearance of a group of large fossils collectively known as the “Ediacaran biota.”, There is evidence that Earth's first mass extinction happened during when early animals changed most regions of the environment. There was a lot of information that was contained within the past 40 million years but as time developed during those seasons earth's environmental climate had changed over periods of Earth-years, what we know back then is that it was not the same as now but millions of years ago appeared something extraordinary:
- The animals were beginning to evolve shells with the appearance of exoskeletons.
- Back then the earth was generally colder during the early Cambrian period.
- Earth was cold probably due to the ancient supercontinent Gondwanan covering the South pole cutting of polar ocean currents.
- In some places the average temperature was 7 degrees Celsius higher then now.
- There were likely more polar Ice caps and series of glaciations back then.
- Earth was still recovering form a snowball planet in it's seasons.
- Most animal species were mainly aquatic during the Cambrian period.
so we grasped a lot information of what the planet habited in those millions of years of what the process earth habited, it had more glaciers most of the species back then were aquatic so marine life adapted to those environments , our planet was more decreased in temperature to an Ice world and animals had shells with exoskeletons, that was this period.
So while during the Ordovician times 100 million years after the dun of the Ediacaran period life continued to flourish as well many of the organisms roamed other regions with different tree spouts growing in areas of places where carbon dioxide is located and then convert it in food which is glucose, where life flourished many creatures, bacteria and spouts habited with new conditions at the climate different changes that happens to earth's new habitats are created. During Ordovician the seas were a diverse group in the regions showing variety of marine species, algae, spouts bacteria with land growth but as many regions began to bring more diverse oceans expanding different creatures, bacteria and algae during this expanse algae was the only multicellular plant, at that time many mollusks and arthropods thrived in most of the oceans as well as some other marine species, but as time grew different creatures had evolutions in their chromosomes giving their DNA new structures to be able to evolve on land, as it goes time has not developed complex life on land yet within that time. Things were good while time developed in Ordovician period the diversity of life in continued the Ordovician Biodiversification Event considerably increases the diversity of life.
Little known fact:
Fish were the world's first true vertebrates that continued to evolve continued to evolve, and those with jaws may have first appeared late in the period:
but still life yet to diversity on land for many creatures still had time to evolve making then adapt to conditions on dry surface and about About 100 times as many meteorites struck the Earth per year during the Ordovician compared with today.
Throughout this period different types of regions of organisms and algae were beginning to settle down when the climates were just beginning to get calmer there were still regions where certain temperatures decreased meaning that areas with decreased temperatures could have made more glaciers with Ice caps, as the Ordovician time progressed we see evidence of glaciers on the land we now know as Africa and South America which were near the South Pole at the time and covered by Ice caps. In the events of this time many changes would taken place with continents shifting and climates differentiating in temperatures but what really happened is the start of the Silurian period, this time was known as Ordovician-Silurian extinction event recently took place and wiped out 60 to 70% of all species and a significant evolutionary milestone during the Silurian times.
Through the time of our planet there has different events occurring within different periods in time like something happening in a extinction event or new climates changing or shiftiness within the tectonic plates holding parts of its mass and when there tectonic movement happening in the earth's mantle, it could result in a supercontinent forming with the result of new temperatures in most regions and that's why different species and algae end up habiting many land marks. In new periods a whole new environments with many habitats comes new land organisms making their homes in lots of locations with this new environments came a different time called the Permian period. The concept of the Permian was introduced in 1841 by geologist Sir Roderick Murchison, who named it after the Russian city of Perm, the Permian witnessed the diversification of the early amniotes into the ancestral groups of the mammals, the world at the time dominated by two continents known as Pangea and Siberia surrounded by a global ocean called Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. Amniotes, who could better cope with these drier conditions, rose to dominance in place of their amphibian ancestors
during this time since there happened to be another supercontinent average temperatures would have increased making Pangea one hot supercontinent with the regions clumped together the Pacific ocean was more expanded back then, extreme conditions in the environment of polar Ice caps and deserts limited the extent of plant life, but amphibious tetrapod's and retiles diversified where plants grew. Oceans teemed with fish and invertebrate life.
Time went on in the late Permian period many plant life was limited through more diverse Ice caps and deserts growing and animals began to spread out where algae and plants grew, something catastrophic occurred.
Earth has gambled a lot of periods having many temperature changes in the environment this ended in a lots of different climates throughout earth's periods but the changes that sometimes happens can be deadly, Extreme conditions such as polar ice caps and deserts limited the extent of plant life, but amphibious tetrapod's and reptiles diversified where plants grew. Oceans teemed with fish and invertebrate life. through the late Permian period was an event that was quite a scare the Late Permian. The greatest mass extinction in Earth's history, the Permian-Triassic extinction event, colloquially known as the great Dying, is about to take place driving 90% of species extinct. For large herbivorous reptiles, and removed habitat for insects.
Resulting it the greatest extinction event of all time throughout the regions!.
Well Earth is quite an interesting terrestrial massive rock hiding inner secrets of the past and revealing some of it's great history with having different organisms to extinctions supercontinents to a diverse species of bacteria and many types of plants and algae being spread to many regions with continents breaking apart and including lots of mystery's to its ancient past its great to say that this one out of billion planet is one great piece of work! for a planet that is.
I'm Tom Kobani and it's be a pleasure telling you about the ancient past of what uncovers this massive rock with many of its glorious wonders of mystery while hiding some of its true secrets of the past and lots discoveries with the earth's mantle temperature and climate.
See in the future.....maybe in the next 500 years or maybe not a human lifespan is 90 or more years so see you the afterlife I suppose of there even is one...
I'm Tom Kobani wow See you next time!.
after 66 million years eventually leading...….today!
